This is what they say
Carl Martin delivers with their power supply with isolated outlets and high current, a stable power supply to cover most power needs. And 180 dollars for a power supply with these specifications shall be considered a good price. Compared with other power supplies is its current slightly larger, and supplies with isolated outlets are hard to find for the same price. In return, you have no opportunity to run pedals on AC power with Pro Power, which can be done in some other power supplies. Is it important for one to be able to adjust the current of the pedal to simulate a flat battery the Pro Power is not obvious either. In contrast, Carl Martin Pro Power is obvious if you need a power supply of high quality without frills, and especially if you have a great deal of 12V pedals.
